Trackpad Problem

Software Ground Control
1

Hi im using Linux, i suspect i had a problem with MTDMotionEvent, when i open Ground Control, in my laptop the area move as i move my finger (without select)

I can see this error after the area stopped moving:

Exception in thread Thread-1:

Do you see any bad behavior withing Ground Control or just the error messages?

Was working fine, but after 1 cut, i can connect to the maslow port, but in my other linux computer debian too, work fine.

In my laptop with linux, the weird thing is, area seems always select, when i move the trackpad the area moves, and the buttons are ramdomly clicked

pip freeze:

appdirs==1.4.3
Cython==0.25.2
docutils==0.15.2
Kivy==1.9.1
Kivy-Garden==0.1.4

It’s working now, was Kivy problem with my trackpad

In file $HOME/kivy/config.ini

Removed %(name)s = probesysfs in
[input]
mouse = mouse
%(name)s = probesysfs

The ramdom clicks prevent maslow from connecting
